NCT01210261

Brief Summary

Obstructive sleep apnea (OSA) is a condition of disordered breathing characterised by intermittent partial and/or complete upper airway obstruction during sleep. The participants, naive to nasal continuous positive airway pressure (CPAP), recently diagnosed with OSA, will undergo two automatic CPAP titration studies with collection of polysomnographic (PSG) data. The data will be analysed to assess effectiveness of Compumedics auto-CPAP device in the normalisation of sleep disordered breathing in OSA patients, with respect to another auto-CPAP device.

Outcome Measures

Primary Outcomes (1)

  • Apnea Hypopnea Index (AHI) difference between test and reference APAP treatment

    AHI is the number of apnea and hypopnea events per hour of sleep

    Up to 8 weeks after study completion

Secondary Outcomes (7)

  • AHI difference between test treatment and baseline

    Up to 8 weeks after study completion

  • Arousal Index (AI) differences between the test and reference APAP treatments and between the test treatment and baseline

    Up to 8 weeks after study completion

  • Respiratory Disturbance Index (RDI) differences between the test and reference APAP treatments and between the test treatment and baseline

    Up to 8 weeks after study completion

  • Sleep Efficiency (SE) differences between the test and reference APAP treatments and between the test treatment and baseline

    Up to 8 weeks after study completion

  • Oxygen desaturation index (DI) differences between the test and reference APAP treatments and between the test treatment and baseline

    Up to 8 weeks after study completion

  • +2 more secondary outcomes

Study Arms (2)

Autoset S8

ACTIVE COMPARATOR

Single night auto-titrating CPAP treatment using the reference device (Resmed Autoset S8) with polysomnographic monitoring

Device: Resmed Autoset S8 - Auto-titrating CPAP

Somnilink SPAP

EXPERIMENTAL

Single night auto-titrating CPAP treatment using the test device with polysomnographic monitoring

Device: Compumedics Somnilink SPAP - Auto-titrating CPAP

Interventions

Subjects will undergo the auto-titrating CPAP treatments in the Monash Sleep Centre with the test and reference devices during two nights in random order. There will be an interval of at least seven days between the two treatments to eliminate the carryover effect. Full polysomnographic (PSG) recording will be conducted during both treatment nights. The recorded physiological signals during PSG will include signals identical to those used during the baseline diagnostic PSG. The patients fill KSS questionnaire immediately after the PSG study. All PSG recordings (both treatment studies and the baseline diagnostic study) will be scored according to the AASM rules by the same sleep technician blinded to the presence and type of auto-titrating CPAP treatment.
